MECHANISM FOR PREVENTlNG THE PULSATION OF BURNING JETS IN VAPOR-STOVES.

SPECIFICATION forming part of Letters Patent No. 398,690, dated February 26, 1889.

Application filed January 24, 1889. $eria1 No. 297,466. (No model.)

To all whom, it may concern;

Be it known that I, Gnonen W. BILLINGS, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and Improved Mechanism for Preventing the Pulsations of Burning Jets in Vapor-Stoves; and I do hereby declare that the following is a full, true, and exact description thereof.

My invention relates to certain means arranged to produce a steady flame from the burner and a uniform outflow or escape of vapor through the needle-valve to the burner for the purpose of preventing the pulsations of the burning jets.

In ordinary burners the pulsation or gush of jets is caused by quick and alternating generation of vapor from the gasoline when the liquid comes in contact with the heated metal of the standpipe or generator. It is the purpose of my invention to avoid this by an auxiliary tube arranged within the standpipe, in which the fluid from the reservoir must first ascend and overflowbefore it comes in contact with the stand-pipe. Between the stand-pipe and auxiliary tube is formed an annular chamber into which the gasoline from the auxiliary tube flows, and while doing so is converted into a steady and uniform flow of vapor tor the burner.

That this improvement may be more fully understood, reference will be had to the accompanying drawing, which represents a side elevation of a \apor-lmrner and a partial central section through the stand-pipe and auxilia-ry tube thereof.

Like letters of reference refer to like parts in the drawing and specification.

A represents the burner. B is the vaporinlet pipe, and C the burner-cap thereof.

The stand-pipe D is arranged at the side of the burner, and connected therewith by the usual means, as shown. The lower end of the pipe is fitted into the branch coupling E, which connects with the induction-pipe a, leading from the reservoir. This branch coupling E is so constructed as to receive and hold in position the auxiliary tube F within the stand pipe D, as shown. From the straight port-ion b of said coupling extends up in a right. angle, or nearly so, thebranch c. The

bore of said branch is smaller near the junc' tion of the branch and the transverse coup ling part, with which the lower end of the auxiliary tube F is connected. The portion a above the connection with the tube F is enlarged to a size for the fitting or attachment of the stand-pipe, which pipe is secured therein, as seen. The tube F set in open relation with the valve-openin g d, and by the adjustable valve-screw K the quantity of gasoline passing through said opening is governed. By this construction the liquid from the reservoir must first ascend within the tube F and overflow into the annular chamber H before it can come in contact with the standpipe D, thus instantaneous generation of vapor does not ensue and pulsation of the burner-j ets is avoided, supposing the burner to be in practical heating operation.

The pipe D, which, while the burner is in operation, becomes exceedingly hot, willheat up to a certain extent the tube F and raise thetelnperature ot the liquid indirectly. Thus while the latter is overflowing down on the tube F and toward the lower end of pipe D the generation of the liquid into vapor can not be instantaneous, inasmuch as theliquid does not come in contact with its surrounding heated pipe D. The pipe D only promotes the progress of vaporization of the gasoline while running down on. the tube F, and the pressure, which is created by the expansion of the gasoline into vapor, regulates the overflow of gasoline from the auxiliary tube F-that is, the gasoline from the reservoir, located above the burners, in the attempt to rush out through the tube F is retarded within said tube by the pressure of the vapor, allowing only an overflow of gasoline enough to compensate the consumption of vapor by the burner.

In burners with ordinary stand-pipes the pulsation of the jets is induced by the direct or intermittent contact of the gasoline with the heated metal of the stand-pipe, which causes instantaneous evaporization, causing gusts and pulling of the burning jet and ex pulsion of vapor out of the stand-pipe. As soon as the jet is beginning to diminish the gasoline attempts to rush into the overheated stanc'tpipe again, resulting in another overproduction of vapor and consequent pulsation of the jet of more or less force. By the application of my invention sudden over-generation of vapor is avoid ed and the attending pulsations therefrom obviated.

\Vhat I claim, and desire to secure by Letters Patent, is

In combination with a Vapor burner, a stand-pipe, an auxiliary tube, F, Within the stand-pipe and forming an annular chamber, H, between the said auxiliary tube and the l l l
